Techniques described herein may be used to condense a large quantity of Virtual Network Function (VNF) chains (that each correspond to a network service) into a much smaller quantity of VNF records; and extract any of the large quantity of VNF chains from the smaller quantity of network service records. This may be accomplished by assigning a Number (No.) of Services attribute and a Tier attribute into each VNF record. The No. of Services attribute and Tier attribute may enable the VNF records to reference one another such that the larger quantity of VNF chains may, in effect, be entirely represented by the much smaller quantity of VNF records, thereby conserving storage space, streamlining VNF chain management, and reducing the processing and memory capacity required to search, configure, and deploy virtual network services.

10. The non-transitory computer-readable medium of claim 8 , wherein the processor-executable instructions further include processor-executable instructions to: receive deployment instructions for automatically deploying each VNF, of the plurality of VNFs, of each VNF chain, within a cloud computing environment; and associate the deployment instructions with the plurality of records.
11. The non-transitory computer-readable medium of claim 8 , wherein the processor-executable instructions further include processor-executable instructions to: receive network descriptor information that describes a network context in which each network service, of the plurality of network services is to be provided; and associate the network descriptor information with the plurality of VNF records.
12. The non-transitory computer-readable medium of claim 8 , wherein the processor-executable instructions further include processor-executable instructions to: receive function type information that describes a functional category for each VNF, of the plurality of VNFs; and associate the function type information with the plurality of VNF records.
13. The non-transitory computer-readable medium of claim 8 , wherein the processor-executable instructions further include processor-executable instructions to: receive a request to deploy a particular network service; identify, based on the request, one or more records, of the plurality of records, that correspond to the network service; and deploy an instance of the particular network service based on the identified records.
14. The non-transitory computer-readable medium of claim 6 , wherein the network service is configured to be part of a software-defined network (SDN).
15. A method, performed by a device, comprising: identifying, by one or more processors of the device, a plurality of Virtual Network Function (VNF) chains, wherein each VNF chain, of the plurality of VNF chains, includes a plurality of VNFs in a sequence that is different from sequences of VNFs included in other VNF chains of the plurality of VNF chains; determining, by the one or more processors of the device, a respective identifier for each VNF, of the plurality of VNFs; determining, by the one or more processors of the device, a sequential position of each VNF, of the plurality of VNFs, in each respective sequence of VNFs included in each VNF chain; and creating, by the one or more processors of the device, a plurality of records based on the VNF identifiers and the determined sequential positions of each VNF, of the plurality of VNFs, in each VNF chain, wherein each record, of the plurality of created records, represents a particular VNF at a particular position within sequences of multiple VNF chains of the plurality of VNF chains.
